Average car emits 4.6 metric tons of CO2 annually
It takes 23 trees to offset 1 ton of CO2 annually
Improving MPG by 5 saves 250 gallons yearly
Fill your tank completely and reset your trip meter. Drive normally until you need to refuel. Divide the distance traveled by the fuel used to refill: Mileage = Distance ÷ Fuel Used. Repeat this process several times for accurate average.
City mileage is typically 15-35% lower due to frequent stops, idling, and acceleration. Highway mileage is higher because of consistent speeds and fewer stops. Most vehicles show both ratings for accurate planning.
Improving from 20 MPG to 25 MPG saves approximately $200 annually (15,000 miles at $3/gallon). Going from 25 MPG to 30 MPG saves about $150 yearly. Small improvements add up significantly over time.
Top strategies include: maintaining proper tire pressure, reducing aggressive driving, removing excess weight, using cruise control on highways, and keeping up with regular maintenance.
Using AC can reduce fuel economy by 5-25% depending on vehicle size and outside temperature. At highway speeds, using AC is more efficient than open windows, which create drag. In city driving, open windows are usually better for fuel economy.
Avoid rapid starts and hard braking to save 10-40% fuel
Keep tires properly inflated for 3% better mileage
Remove unnecessary items - 100 lbs reduces MPG by 1%
Combine errands to avoid multiple cold starts
